It'd be cooler if it kept multiple balls in the air at one time.

It was interesting to realize that the ball is being shot across the wheel, and the wheel has to get in position to catch it. Angular momentum and projectile motion and centripetal force and all that. Fascinating to watch, even without the physics.

I like the weird wobbling effect as the cone speeds past the camera. I've seen a similar warping effect with someone taking a picture of a propeller in-flight with their camera phone.

That is really cool, and some impressive calibration. The video gave me a bit of motion sickness!
